PROBLEM TO BE SOLVED: To suppress powders collected in a collection container from flowing in a reverse flow from a collection hole.SOLUTION: A powder collection device comprises: a collection container 1 for collecting powders G which have been used and transported from a powder processing part 10 and storing the powders G in a powder storage chamber 3; plural collection holes 2 arranged in an upper position of a powder maximum storage position of the powder storage chamber 3 in the collection container 1, and over a longer direction of the collection container 1, and collecting the used powders G transported from the powder processing part 10; a transport member 7 which is provided in the collection container 1 along a longer direction of the collection container 1, and transports the powders G stored in the powder storage chamber 3 so as to level the powders G; and plural air extraction holes 8 arranged and distributed in regions sandwiching a center Oc of the longer direction of the collection container 1, on the collection container 1, disposed above the transport member 7, and disposed on positions deviated from falling paths of the powders G from respective collection holes 2 and on positions which are not above a vertical lower end position of at least one of the adjacent collection holes 2.SELECTED DRAWING: Figure 1 【課題】回収容器内に回収した粉体が回収口から逆流することを抑制する。【解決手段】粉体処理部１０から搬送された使用済みの粉体Ｇを回収して粉体収容室３に収容する回収容器１と、回収容器１のうち粉体収容室３の粉体最大収容位置よりも上側の位置で且つ回収容器１の長手方向に亘って複数設けられ、粉体処理部１０から搬送された使用済みの粉体Ｇを回収する複数の回収口２と、回収容器１内に当該回収容器１の長手方向に沿って設けられ、粉体収容室３に収容された粉体Ｇを均すように搬送する搬送部材７と、回収容器１のうち少なくとも当該回収容器１の長手方向の中央Ｏｃを挟んだ領域に分かれて設けられ、搬送部材７よりも上方に位置し、各回収口２からの粉体Ｇの落下経路から外れた位置で且つ近接する回収口２の少なくとも一つの鉛直方向下端位置を超えない領域に開設された複数の空気抜き口８と、を備える。【選択図】図１
